photoreception

If so, it would mean that photoreception had been re-established.

In plants, blue light photoreception can be used to cue developmental signals.

The third eye represents evolution's earlier approach to photoreception.

Exactly how this extraocular photoreception works is still unknown.

Photoreception is phylogenetically very old, with various theories of phylogenesis.

Importantly, the mechanism of insect photoreception is dramatically different from that in mammals.

Others work on photoreception, photoperiodism and the circadian rhythm.

Opsins are the pigments involved in photoreception.

There is evidence that InsP 3 functions in sensory perception (taste, olfaction and invertebrate photoreception).

The failure of cry mutants to synchronize to light dark cycles indicates that cryptochrome's normal function involves circadian photoreception.

Lysine 296, in rhodopsin, is bound to retinal via Schiff base and is key for the photoreception mechanism.

Despite much research on the topic, cryptochrome photoreception and phototransduction in Drosophila and Arabidopsis thaliana is still poorly understood.

The term is generally applied to the non-protein chromophore moiety of photosensitive chromoproteins, such as the pigments involved in photosynthesis and photoreception.

Taking due cognisance of biochemical pathways, the authors conclude that only substances metabolically convertible to vitamin A are capable of restoring photoreception.

They are based on an agreed-upon standard luminosity function which is based on measurements of the spectral characteristics of visual photoreception in many individual human eyes.

The 24-hr rhythm could be reset by light via the protein cryptochrome (CRY), which is involved in the circadian photoreception in Drosophila.

In November 1998, Rosbash et al. discovered the cry Drosophila mutant, which lead to the conclusion that cryptochrome protein is involved in circadian photoreception.

Fuligo septica contains a yellow pigment called fuligorubin A that is thought to be involved in photoreception and in the process of energy conversion during its life cycle.

Thomas's partial list of Ca-dependent events includes muscle contraction, neurotransmission, photoreception, cell division, secretion, cilia, cyclic AMP, and important kinases.

The optic lobe primordium and brain of late third instar larvae have only limited functions in larval photoreception and contain only a small number of mature neurons.

Even one-celled animals may have light-sensitive areas, but the true elaboration of course comes in multicellular animals, in THE HUMAN BBAIN which discrete organs - eyes - are devoted to photoreception.

About six years ago, explains Zuker, who previously worked on other sensory systems in flies, 'there was a disconnect between our understanding of sensations in the case of photoreception, mechanoreception, touch, and so on and what we knew about taste'.

The SCN is known to be involved not only in photoreception through innervation from the retinohypothalamic tract, but also in thermoregulation of vertebrates capable of homeostasis, as well as regulating locomotion and other behavioral outputs of the circadian clock within ectothermic vertebrates.

Hartline shared the 1967 Nobel Prize with summer MBL colleague George Wald, who described the molecular basis of photoreception by showing that the light-sensitive visual pigment molecules consist of a slightly modified form of vitamin A coupled to a protein.
